Stop the favoritism on one driver which helps another, but not another driver.
Stop giving employees Hope's of employment guarantee there work. Pay should be the same unless qualified. And work to improve your companies name.

I've only worked for good and reliable employers.
Get rid of the supervisor has his favourites and one employee who talks down to you.
Put a lot more focus in highlands
